Describe some of the problems faced by benthic organisms in the ocean. plz need imidiately

Benthic organisms live on the ocean floor, where photosynthesis cannot occur. Since they cannot feed on any plants or living things that require photosynthesis to live, they must feed on either falling nutrients or on each other. due to the lack of a stable food source, life progresses slowly and survival isn't a promise. 

Sorry my friend i don't know the answer. i am just in 6th

Your answer is c. explanation: plasma  is the fourth state of matter, derived from the gaseous state of matter.  plasma  can contain free  electrons  and/or  ions. while  plasma is never neutral, it can either be positively or negatively charged.  gases, however, are electrically neutral.
